Auto TextBack – Missed Call SMS

What is Auto TextBack?

Auto TextBack is a lightweight utility that watches for incoming calls and, when a call is missed, sends a pre‑written text message to the caller. It works entirely on the device, without requiring an internet connection or a user account.

Main features

• Custom reply message – Write any text you prefer, in any language, and have it sent automatically.
• One reply per number – The app ensures that each caller receives only a single auto‑reply within a configurable time window, preventing repeated messages.
• Usage limits – Set daily or monthly caps on the number of SMSes the app can send, helping you stay within your messaging budget.
• Character counter – See how many characters your message uses, keeping it within the standard 160‑character SMS length.
• Privacy‑focused – No data leaves your phone, and the app does not collect analytics or display ads.

How it works

When a call arrives, Android notifies the system of the call state. Auto TextBack monitors this state in the background. If the call ends without being answered, the app triggers the SMS engine and sends the stored reply to the caller’s number. The process runs silently, requiring only the permissions needed to detect call state and access the call log for the missed‑call number.

Practical uses

• Busy professionals can let clients know they’ve seen the call and will respond later.
• Small business owners can provide an immediate acknowledgment to every inbound inquiry.
• Drivers or meeting attendees can avoid the temptation to check their phone while focusing on other tasks.

Installation information

Search for Auto TextBack – Missed call SMS in the Google Play Store, install the free app, and grant the requested permissions. After the initial setup, type your preferred reply, enable the toggle, and the app begins operating in the background.

Things to know before installing

• The app needs permission to read phone state and the call log; these are essential for detecting missed calls.
• SMS charges apply according to your mobile plan; use the usage‑limit feature to control costs.
• Because the app works offline, it does not require any network access to function.

Who may find it useful?

Anyone who frequently misses calls and wants to acknowledge callers promptly can benefit from Auto TextBack. This includes professionals, entrepreneurs, students, and anyone who values a quick, automated response without manual effort.

Frequently asked questions

Do I need an internet connection?

No. The app sends SMS messages directly through your carrier’s service, so it works without data.

Can I change the reply message later?

Yes. Open the app at any time, edit the text, and the new message will be used for subsequent missed calls.

Will the same caller receive multiple messages?

The app limits replies per number within the time window you set, so a caller will not be spammed with repeated texts.

Is my personal data collected?

All settings and messages are stored locally on your device. The app does not transmit any personal information.
